VB转C＃转换问题 [英] VB to C# conversion problem

问题描述

我在Asp.Net工作 - C＃。



我在VB&运作良好

I'm working in Asp.Net - C#.

I've a coding in VB & is working well

Dim CLEAD As XmlSchemaElement
.
.
.

  reader = New XmlTextReader(xsdFilePath)
            schema = XmlSchema.Read(reader, Nothing)

            For i As Integer = 0 To schema.Items.Count - 1
                If TypeOf schema.Items(i) Is XmlSchemaElement Then
                    CLEAD = schema.Items(i)
                End If
            Next

我尝试将其转换为c＃，如下所示

I tried to convert it into c# as follows

XmlSchemaElement CLEAD;
.
.
.
reader = new XmlTextReader(xsdFilePath);
 schema = XmlSchema.Read(reader, null);

 for (int i = 0; i < schema.Items.Count-1; i++)
            {

                 if (schema.Items[i].GetType() == typeof(XmlSchemaElement))
                     CLEAD = schema.Items[i];
            }

但这一行（CLEAD = schema.Items [i];）给出错误：无法隐式转换系统.Xml.Schema.XmlSchemaObject到System.Xml.Schema.XmlSchemaObjectElement



请帮我纠正这个

But this line (CLEAD = schema.Items[i];) gives the error: cannot implicitly convert System.Xml.Schema.XmlSchemaObject to System.Xml.Schema.XmlSchemaObjectElement

Please help me to rectify this

推荐答案

你可以明确地表达它（你已经检查了它的类型），例如

You may explicitely cast it (you've already checked its type), e.g.

CRMLEAD = (XmlSchemaElement)schema.Items[i];

或您可以使用作为运算符（参见MSDN [ ^ ]）。

or you maight use the as operator (see MSDN[^]).
